How to Make Textures for 3D Models: Basics and Tips

Texturing is a very important part of the 3D modeling process. All of the finer characteristics of characters in 3D modeling, such as wrinkles and individual carpet threads, are the product of texture applied by a 3D artist. Usually, the 3D models created are in a programs default flat grey color. 2D photos must be set out on 3D models to add colors, designs, and textures. Adding colors or surface and material properties to a 3D model requires another step forward in the 3D modeling pipeline i.e. 3D texturing.

Types of 3D textures and materials

Before you start texturing, its better to decide what type of material and 3D texture to use. Here are some common types of materials and textures that you can use for your 3D models:

Basic material

This is a smooth material made using just color and convex. Its a good basis for texturing to achieve the realistic look of an object. It can also be used in game design if an item doesnt require any interactions with characters and fits into a game environment.

PBR material

Physically-based rendering (PBR) material is textured enough to look natural. To achieve this result, artists use color, albedo (light reflection effect), roughness, and bump map textures. All of these features complement the material to match its desired appearance.

Solid texturing

In three-dimensional space, color variations are adjusted at each point of the model instead of overlaying two-dimensional textures one on one. As a result, color and gloss change depending on their position on the map.

Geometric texturing

In this case, real images can be superimposed on the surface of the 3D object. In addition, the texture is adjusted by changing the geometry of the objects surface.

Stages of 3D texturing

Textures are 2D in format, but texturing only begins with the creation of a 3D model. The model is analyzed, and followed by several steps of texture design. Lets take a look at the main stages of standard texturing.

UV unwrapping

The texturing process should start with the unwrapping of a complete 3D model. Such a flat display of the model is called a UV map, where U and V are the coordinate axes of two-dimensional space, in contrast to the 3D model, which is displayed as X, Y, and Z.

What is UV unwrapping?

UV unwrapping is the process of projecting a 2D image onto a 3D model's surface. The UV map defines how each polygon of the model corresponds to a pixel or texel of the image. UV unwrapping can be done manually or automatically by using software tools.

Why is UV unwrapping important?

UV unwrapping is important because it allows you to apply textures to your 3D models in a precise and consistent way. Without UV unwrapping, your textures would look distorted, stretched, or misaligned on your model. UV unwrapping also allows you to optimize the use of texture space and reduce the file size and memory usage of your textures.

Baking

After unwrapping the model, you need to bake the textures. Baking is the process of transferring the details of a high-poly model to a low-poly model using a texture map. This way, you can create realistic-looking models without using too many polygons, which can improve the performance and rendering speed of your 3D scene.

What is a high-poly model?

A high-poly model is a 3D model that has a large number of polygons, which are the basic units of 3D geometry. High-poly models can have more details and smoother surfaces, but they also require more computing power and memory to render.

What is a low-poly model?

A low-poly model is a 3D model that has a small number of polygons, which are the basic units of 3D geometry. Low-poly models can have less details and more angular surfaces, but they also require less computing power and memory to render.

What is a texture map?

A texture map is an image that is applied to the surface of a 3D model to add color, detail, or other effects. There are different types of texture maps, such as diffuse, normal, specular, ambient occlusion, etc. Each type of texture map affects a different aspect of the appearance of the model.

Painting

The next stage is painting the textures on the UV map. Painting is the process of adding colors, patterns, or images to the texture map using software tools. Painting can be done manually or automatically by using brushes, stamps, filters, or generators. Painting can also be done in 3D mode by applying the textures directly on the model.

What are some software tools for painting textures?

There are many software tools for painting textures, such as Substance Painter, Photoshop, Blender, GIMP, etc. Each tool has its own features and advantages, depending on your needs and preferences. Some tools are more specialized for 3D texturing, while others are more general-purpose for 2D editing.

What are some tips for painting textures?

Some tips for painting textures are:

• Use reference images or photos to get inspiration and guidance for your textures.

• Use layers and masks to organize and edit your textures without affecting other parts.

• Use different blending modes and opacity levels to create different effects and transitions.

• Use custom brushes or stamps to create unique shapes and patterns.

• Use filters or generators to add noise, grunge, or other effects to your textures.

Shading

The final stage is shading the textures on the model. Shading is the process of adding lighting and material effects to the textures using software tools. Shading can make your textures look more realistic and dynamic by simulating how they react to different light sources and environments.

What are some software tools for shading textures?

There are many software tools for shading textures, such as Substance Designer, Blender, Maya, Unreal Engine, etc. Each tool has its own features and advantages, depending on your needs and preferences. Some tools are more specialized for creating procedural materials, while others are more general-purpose for rendering 3D scenes.

What are some tips for shading textures?

Some tips for shading textures are:

• Use PBR materials to create realistic and consistent textures that work in any lighting condition.

• Use normal maps to add depth and detail to your textures without increasing the polygon count.

• Use specular maps to control how shiny or reflective your textures are.

• Use ambient occlusion maps to add shadows and contrast to your textures.

• Use emissive maps to make your textures glow or emit light.

Best practices and tips for 3D texturing

To make your 3D texturing process more efficient and effective, you should follow some best practices and tips. Here are some of them:

Resolution

The resolution of your texture determines how sharp and detailed it looks on your model. You should choose a resolution that matches the size and importance of your model in your scene. For example, if your model is small or far away from the camera, you can use a lower resolution texture to save memory and performance. If your model is large or close to the camera, you can use a higher resolution texture to avoid pixelation and blurriness.

Tiling

Tiling is the repetition of a texture across a surface. Tiling can be useful for creating seamless patterns or covering large areas with a small texture. However, tiling can also create unwanted artifacts or patterns that look unnatural or boring. To avoid this, you should use textures that have minimal seams or variations. You can also use different techniques to break up the tiling effect, such as using decals, masks, overlays, or randomization.

Lighting

Lighting is a crucial factor that affects how your textures look in your scene. Lighting can create shadows, highlights, reflections, colors, and moods that enhance or change the appearance of your textures. You should consider how your textures react to different light sources and environments, and adjust them accordingly. You can also use different texture maps to control how your textures respond to lighting, such as normal maps, specular maps, ambient occlusion maps, etc.

How do I apply textures to 3D models?

To apply textures to 3D models, you need to use a 3D software or tool that supports texturing. Depending on the software or tool, you may need to follow different steps or methods to apply textures to your models. However, the general process is usually similar to this:

• Create or import your 3D model into the software or tool.

• Unwrap your model into a UV map, which is a flat representation of your model's surface.

• Create or import your texture image into the software or tool.

• Assign your texture image to your UV map, which will project the image onto your model's surface.

• Adjust the scale, rotation, position, and other parameters of your texture image to fit your model's shape and size.

• Save and export your textured model as a file format that supports textures, such as OBJ, FBX, GLTF, etc.

How do I make my own textures for 3D models?

To make your own textures for 3D models, you need to use a software or tool that allows you to create and edit 2D images. You can use any image editing software, such as Photoshop, GIMP, Paint.NET, etc., or you can use specialized software for 3D texturing, such as Substance Painter, Substance Designer, Blender, etc. The process of making your own textures may vary depending on the software or tool you use, but here are some general steps you can follow:

• Decide what type of texture you want to make, such as diffuse, normal, specular, etc.

• Create a new image file with the desired resolution and color mode.

• Use various tools and techniques to draw, paint, or generate your texture image. You can use brushes, filters, gradients, patterns, noise, etc. You can also use reference images or photos as a source of inspiration or guidance.

• Save and export your texture image as a file format that supports textures, such as PNG, JPG, TGA, etc.

How do I optimize my textures for 3D models?

To optimize your textures for 3D models, you need to consider some factors that affect the quality and performance of your textures. Here are some tips on how to optimize your textures:

• Choose the appropriate resolution for your texture image. Too low resolution can make your texture look blurry or pixelated. Too high resolution can make your texture take up too much memory or loading time. You should balance the resolution with the size and importance of your model in your scene.

• Choose the appropriate file format for your texture image. Different file formats have different advantages and disadvantages in terms of compression, quality, and compatibility. You should choose a file format that suits your needs and preferences. For example, PNG is a lossless format that preserves the quality of your texture, but it also has a larger file size. JPG is a lossy format that reduces the quality of your texture, but it also has a smaller file size.

• Reduce the number of textures you use for your model. Too many textures can make your model look cluttered or inconsistent. They can also increase the memory and performance requirements of your scene. You should try to use as few textures as possible to achieve the desired effect. You can also use techniques such as texture atlases, which combine multiple textures into one image, or texture compression, which reduces the file size of your textures.

• Use tiling and repeating textures wisely. Tiling and repeating textures can help you cover large areas with a small texture, which can save memory and performance. However, they can also create unwanted patterns or seams that look unnatural or boring. You should use tiling and repeating textures only when they make sense for your model and scene. You should also use techniques such as offsetting, rotating, scaling, or blending to create variations and transitions.
